Frequent Disconnection on 5G Home Internet

I have had this issue on and off for the last several months of having 5G Home Internet.  I got complacent and ordered a Keep Connect, which is a device that automatically power cycles your modem if internet is lost.  It is up to 300+ resets in the past few months.

I called support today to see if there is anything else that can be done as it seems to be getting worse rather than better.  The support was energetic and helpful and did have new reason for this issue.  They said there is a 'fix' coming to firmware in a few weeks that has something to do with the 2.4GHz and 5.0GHz signals and devices switching back and forth.  I was told I could manually separate devices onto either network to get instant results, but that sounded like too much work so I am gonna wait and hope a firmware fix is weeks away.  Anyone else hearing this?  Is it true?
